一种改进的熄焦车厢门控制系统
本技术涉及一种改进的熄焦车厢门控制系统,属冶金焦化控制设备
技术介绍
在冶金焦化焦炉机车生产作业中,熄焦车通过熄焦车厢接焦后,将焦碳运往熄焦塔熄灭,然后送至焦台放焦完成熄焦作业。熄焦车走行过程的颠簸和熄焦过程中水的冲力都会增大熄焦车厢门受到的外力。熄焦车厢门由电控和气控两个系统进行控制,电控系统如图1所示,由车厢开门按钮SB1、关门按钮SB2、开门继电器线圈KA1、关门继电器线圈KA2、开门继电器常开触点KA1-1、关门继电器常开触点KA2-1、开门电磁阀线圈YV1、关门电磁阀线圈YV2组成,其中开门按钮SB1与开门继电器线圈KA1串接,开门继电器常开触点KA1-1与开门电磁阀线圈YV1串接;气控系统如图2所示,由气动电磁阀、气缸和曲臂机构组成,气动电磁阀为三位五通阀,阀中的开门气路A由开门电磁阀线圈YV1控制打开和关断,通过管路与气缸的一端连接,关门气路B由关门电磁阀线圈YV2控制打开和关断,与气缸的另一端连接,气缸与车厢门曲臂机构连接,曲臂机构与车厢门连接。司机按下开门按钮SB1,接通开门继电器线圈KA1,KA1线圈得电后其常开触点KA1-1闭合,使得开门电磁阀线圈YV1得电,开门电磁阀打开,气路通过图2中的A通道进入气缸中,驱动气缸曲臂机构动作,曲臂机构推动车厢门打开,从而完成车厢开门过程;关门动作与开门动作相类似。现有的熄焦车厢们控制系统存在如下缺点:(1)电控系统容易出现司机误按开门按钮SB1的情况,而当司机误操作时,立刻会使开门继电器线圈KA1得电,开门电磁阀线圈YV1得电,从而开门电磁阀气路接通,直接将 ...
